Graco SlimFit3 LX: Graco's manual sets rear- and forward-facing height by fit (head at least 1″ below the headrest adjustment handle), not a printed inch limit.

Printed verbatim in the manufacturer's manual (NWL0001077519C · Chicco NextFit Zip (03/2019)); “—” = not published for that mode, “not yet sourced” = we haven't read that manual yet, not that the seat has no limit. How we source these →

Recall record

Graco — 17 on NHTSA's record · Chicco — 2 on NHTSA's record.

That is the record of the brand — not a verdict on these models. A recall names specific models and manufacture-date ranges, and a seat missing from the record is not "recall-free": check nhtsa.gov/recalls with the model and date of manufacture on your seat's label.
